      You can use Python-based or Perl-based Scripts, and even Z SQL
      Methods to implement logic. Your logic objects can call each other,
      and can be called from your presentation methods. To create the
      *isHungry* method, first create two new properties in the
      *ExhibitProperties* property sheet named "last_meal_time" that is of
      the type *date* and "isDangerous" that is of the type *boolean*.
      This adds two new fields to your Edit view where you can enter the
      last time the animal was fed and select whether or not the animal is
      dangerous.

         You need to enter a date on the last_meal_time property.
         Zope 2.5.1 will not let you enter a null value in there.

         for example, date should be like bellow:
         2002/08/20 13:00:00 GMT+9
